摘　　要：微波光子技术是一种将微波与光波融合的交叉前沿技术,微波光子系统相比于传统电子系统具有带宽大、质量轻、损耗低、功耗低、抗电磁干扰等优势,在雷达电子战、传感、测量以及通信等领域有广泛的应用场景。基于光纤分立器件的微波光子系统已发展成熟并在相关领域得到应用验证,但是还存在体积大、功耗高、质量重的不足,亟需向微波光子集成芯片发展。本文对微波光子收发芯片、微波光子信号产生芯片、微波光子滤波芯片、微波光子波束形成芯片、微波光子频率测量芯片、可编程微波光子芯片的最新研究进展进行了梳理和分析,并对微波光子集成技术的未来发展趋势进行了展望。Significance Microwave photonics(MWP)is an interdisciplinary and cutting-edge technology that combines microwave and lightwave to generate,transport,manipulate,and measure wide-band radio-frequency(RF)signals.This field has become a focal point of research in recent years.Compared with traditional electronic systems,MWP systems offer advantages such as wide bandwidth,lightweight,low loss,and anti-electromagnetic interference.These unique benefits make MWP highly attractive for various applications including radar,electronic warfare,sensing,measuring,and communication systems.Representative demonstrations include microwave photonic radar system,ultra-wideband radio on fiber(ROF)transmission,high precision optical vector network analyzer(OVNA),ultra-low phase noise RF signal generation,and ultra-wideband RF receiver for electronic warfare.However,these impressive demonstrations are mostly bulky systems composed of discrete fiber components,which still have drawbacks such as large size,high power consumption,large mass,and costliness.They are also sensitive to environmental perturbations like vibrations and temperature variations.Therefore,there is an urgent need to reduce the size of MWP systems for their large-scale applications.Benefiting from the rapid advancements of optoelectronic integration technologies,researchers are dedicated to developing various integrated MWP chips.As known,the key requirements for high-performance MWP systems include high RF gain,low noise figure(NF),and large spurious-free dynamic range(SFDR).These can be translated to the need for low loss,high optoelectronic conversion efficiency,low noise,and high linearity in integrated MWP chips.However,none of the photonic integration platforms such as indium phosphide(InP),silicon on insulator(SOI),silicon nitride(Si_(3)N_(4)),silicon dioxide(SiO_(2)),and lithium niobite(LiNbO_(3))can fulfill all these requirements.Given the inherent limits,numerous integrated MWP chips fabricated on these photonic integration platforms have been developed acc
